To'aZZ whom it mar] concern: )1 5 Be it known that I, CHARLES'A'. MGCANN', a citizen of-the United States,residing at Springfield, in the countyof Sangamonand State of Illinois, have invented a certain new and useful Improvement-in Churns of which the following'is afull; clear5 concise and exact description.

-My inventionrelates to churnsand has an ob ect the provision of operating mechaa nism therefor whereby-the cream container may be-bodily reciprocated and may also be oscillated as it reciprocates By imparting to the container'c'ombined reciprocatory and oscillatory movements the "churning I Operation is very rapidly andmost eflicientlyl performed. The mounting for, the container is such as to permit thecontain'er to be reciprocated and oscillated concurrently and is desirably inclusive oftwo extensible and contractible elastic members (preferably; coiled wire springs) that are anchored "at theirouter ends and are attached at their innerends to the container atone of its ends; preferably the lower end. The, actuating mechanism for concurrently reciprocating and oscillating the container and controlling v the movements thereof is preferably inclubein conformity and enabling the employ -sive of a fly wheel in crankconnection with the upper end of the containegan operatingcrank; andspeed-increasing gearing opera;

tively connecting said operating crank and? a Wheel. By this mechanism the containeris rapidly put through it's 'cyclesof concurrent reciprocatory" and oscillatory movements; the fly wheel furnishingsufl icient momentum to cause -'the repeated cycles of movement' to ment of substantially uniform drivingtorque to the operatingcrank."

My inventionhas been embodied in a hand operated mechanism in which event the oper ating crank lsinclusive of a crank handle 7 inggearing that is actuated by the user t'o'jtu'rn theco'n-' tainer agitating fly wheel through-the" intermediation of the aforesaid "speed fincreas I will explain'myinvention morefnlly by, reference to the accompanying drawing showing T the preferred embodiment thereof and in which Figure 1 is a front elevaton of a churn equipped in accordance with the j invention; -Fig. 2..-is ,a view on line 2.2 of Fig. 1; Fig. 3 is a-viewon line 33 of' Fi .2; and iiigie'c saview, oniai se c. l.

supported. A creamcon'tainer 5, preferably I cylindrical, is removably secured in an up! right rectangular container frame formed of upr-ightflsidesfi, abase 7-, and atop 8. 7 A rod" 9 has its lower :end

threaded, this threaded end ofsaid -rod pass-' ing through the top 8 and being held in: as-

supporting I sembly therewith 'bynuts 10 which are upon; i

the threaded end oftherod' 9 and between whichnuts the top;v -8- is disposed and clampedythe arrangement being such that the'rod 9 is practically in fixed relation with respect to the'container supporting frame; The lower. ends'of the sides 6are laterally extended to form'hooks llthat are in aline ment withthe base]? The inner-ends of the. extensible and contractible elastic members 12 are secured-to the hooks 11 whilethe outer to the legsl and 3 vwhich legs'are so positioned asto bring these elastic members into. alinement with the base 7 ofthe container ends of these elastic membersare anchored- 7 supporting frame: The'elastic: members l2v are desirably in thehaturerof coiled springs of sufiicient strength and" under sufficient V tension 'to cooperatewwith thea actuating; ,7

mechanism; a c

The rod 9 functlons as a p1tman,-Fhav1ng crankconnection i-wi'th the" fly ZwheelQllS through the intermediation' of a crank pin v 14 the pitman 9, the crank pin 14, and the container-supporting frame-constituting the preferred means whereby the container I 5 is brought into 5 crank connection aw-itll the flywheel." i The crank pin 'or connectionaof the fly wheel with the container also takes chine there is employed a crank handle 15 that is attached to an "operating crank 16. "The crank" shaft 17 that carries the crank "partin "supporting"the containeri 'As the machine; illustrated is a vhand' operated maupon the"('zrank shaft i17 and meshes with the spur pini'on"19 fixed upon wheel- 13 and turning upon the fly wheel shaft 13 which the mounting frame; By means of the speed 7 increasing gearing 18 and 1 9 the fly wheel 18 is turned at ahigh' rate of speed with respect to the rotation of the crank shaft 17. p,

This wheel 13 furnishes momentum where by the application of operating torque to the crank 16 may be substantially uniform and whereby the fly wheel load; may be actu: ated by the fly wheel with regularity. The containen a is supported-upon the base -7 of the. container supporting frame that incloses it, the axis of the container intercepting the frame base 7 and beingcoincident with the axislof the pitman rod 9 whereby the springs. l2'are alined with a diametrical line of the bottom of the containerj The container is desirably supplied wlth cream to sixty per cent; of its capacity to get the best results wherea'fter the container lid 20 is applied.

This container lid has/a peripheral groove. 21 that holds arubber gasket 22- and recelves the annular head or rim 23 at the upper end of. the body of the container. The container lid is dished upwardly and has a central seat 203' that receives the correspondingly shaped lower end of a sleeve nut 2i that IS in threaded engagement with the lower end ofthe pitmaii rod 9'. This sleeve nut has a knurled of thereciprocating container. Thebod-y of cream is thus violently shifted longitudie nally with respect to the. container and is laterally violently shifted with respect to sition to which the container is concurrently;

the container, there being also a resultant combinationof these movements imparted to-the cream; i Y

The springs 12 cooperate with the actuating mechanism to relieve it of some of its load, these springstending to-restore; the container to mid-positions. The spring supports 12 may be said to act as a mounting upon which the container floats and in opporeciprocated and oscillated. This container is desirably made of seamless metal, preferably aluminum,-so that itmay readily be cleaned. I 1

lVhile I haveherein shown and particularly described the preferred embodiment ofmy invention I do not wish to be limited to the precise details oii construction shown aschanges may readily be made without de- 1 parting from the spirit of my invention, but
